Miley Cyrus clearly "can't stop" causing trouble  and her upcoming 21st birthday will of course be no exception. 

The unpredictable pop star turns 21 on November 23, and she is reportedly planning a sex-themed birthday party that will take place in a sex dungeon, according to The Sun. Be afraid.

“Miley wants the party to be off the hook,” a source says. Apparently, in Miley's world, a party that doesn't have weird sex stuff going on is way lame.

“She’s hiring all sorts [of performers]," the source continues. "She’s enlisted party planners and asked them [to] create a sex dungeon with cages and whips."

By the way, in case you didn't know, lightbulbs that aren't shaped like genitalia are totally pedestrian. “Penis-shaped party lights and male and female dancers are also on the bill," reveals the insider.

And what's a party without drinks that are named after yourself, right? "She intends to go all out with an open bar filled with Miley-inspired cocktails, too," the source adds.

Wow! Miley's 21st birthday bash is truly going to be a night to remember  or a night to scar everyone for life, depending on how open-minded you are. 

Then again, the fact that Miley is planning a wild birthday shouldn't be a huge surprise. She made headlines last year for provocatively posing with a penis-shaped birthday cake. And she turned heads with her sexy Lil Kim costume at a Halloween party this year.

As for the actual day of her birthday, Miley will be at hard at work, as she'll be busy rehearsing for the AMAs. So perhaps the party will be before her actual date of birth.

So we're curious to see what Miley ends up doing for her birthday. And if you go to her party, you might not want to spend too much time near the lightbulbs. Just sayin'.
